Nano-Graphene Coated Aluminium foil Collector Material for Graphene Lithium Battery supercapacitor (30cm10cm)

Product characteristics: 1. The product uses graphene as raw material to realize ultra-thin coating. 2. It can significantly reduce the interfacial resistance and improve the electrochemical performance of lithium battery, such as the rate and cycle. 3. Improve the adhesion between the active material and the collector, inhibit the corrosion of the collector, and prolong the cycle life of the battery. 4. Reduce polarization, reduce thermal effect, inhibit heating during charging, and improve battery safety. Suggestions for use: 1. The product can be directly used as a collector in lithium-ion batteries or supercapacitors. 2. This product is suitable for various coating methods (such as continuous coating, gap coating, etc.). When coating operation, the ambient temperature of the head and tail of the machine is controlled below 30%. 3. When this product is welded by ultrasonic ear welding, it is recommended that the power of this product be increased by 10% compared with ordinary aluminum foil, and the riveting of the ear is not affected. 4. This product is easy to absorb moisture. Do not open the vacuum package before use. If there is any surplus material after use, it is recommended to put it in the vacuum drying box (40-60 C) for drying for 2 hours before vacuum drying.

• 💎 This product is a new type of collector with graphene coating uniformly coated on the surface of aluminium foil.
• 💎 The product utilizes the excellent conductivity of graphene and two-dimensional lamellar structure to form an ultra-thin coating with excellent conductivity on the collector surface (thickness less than 1um), which can significantly reduce the interface resistance and improve the adhesion of active materials, thereby greatly improving the battery rate performance and cycle life.
• 💎 Its comprehensive performance is superior to that of coated aluminium foil modified with carbon black and graphite. It can be widely used in lithium ion batteries and supercapacitors instead of traditional aluminium foil and corroded aluminium foil.
• 💎 Name: Graphene coated aluminium foil collector; Appearance: Black grey coating
